"A solenoid of 1000 turns per metre has a core with relative permeability 500. Insulated windings of the solenoid carry an electric current of 5A. The magnetic flux density produced by the solenoid is : (permeability of free space = 4$\pi$ $\times$ 10$-$7 H/m)"

Question

Accepted Answer

"B = $\mu$ n i

B = $\mu$_r $\mu$₀ n i

B = 500 $\times$ 4$\pi$ $\times$ 10^$-$7 $\times$ 10³ $\times$ 5

B = $\pi$ $\times$ 10^$-$3 $\times$ 10³

B = $\pi$ T"
